-The emission factors used are results of the adaptation of EMEP/EEA Guidebook defaults (EMEP/EEA, 2023) [(EMEPEEA2023)].+The emission factors used are results of the adaptation of EMEP/EEA Guidebook defaults (EMEP/EEA, 2023) [(EMEPEEA2023)], for our inventory so-called 'apllied emission factors' with following parameters: 
 +\\ 
 +- pollutant-specific emission factor, not corrected for soil moisture and silt content (kg of emitted pollutants/m² affected area/year), 
 +\\ 
 +- average affected area as product of number of buildings constructed multiplied with conversion factor (average affected area per building), 
 +\\ 
 +- duration of construction activity from default values (EMEP/EEA, 2023)[(EMEPEEA2023)], 
 +\\ 
 +- specification of precipitation-evaporation index and soil silt content as constants, 
 +\\ 
 +- efficiency of emission control measures at the moment see FAQ below.

-However, further assumptions were necessary in order to calculate: 
- 
-For example, the emission factors are adapted with correction factors of (i) 0.20 for the moisture level and (ii) 2.22 for the silt content. 
-  
-The assumption about the duration of the construction activity uses default values from (EMEP/EEA, 2023)[(EMEPEEA2023)]:
